RIKEN KEIKI Co WACC % Calculation

The weighted average cost of capital (WACC) is the rate that a company is expected to pay on average to all its security holders to finance its assets. The WACC is commonly referred to as the firm's cost of capital. Generally speaking, a company's assets are financed by debt and equity. WACC is the average of the costs of these sources of financing, each of which is weighted by its respective use in the given situation. By taking a weighted average, we can see how much interest the company has to pay for every dollar it finances.

WACC=E/(E + D)*Cost of Equity+D/(E + D)*Cost of Debt*(1 - Tax Rate)

1. Weights:
Generally speaking, a company's assets are financed by debt and equity. We need to calculate the weight of equity and the weight of debt.
The market value of equity (E) is also called "Market Cap". As of today, RIKEN KEIKI Co's market capitalization (E) is 円157504.292 Mil.
The market value of debt is typically difficult to calculate, therefore, GuruFocus uses book value of debt (D) to do the calculation. It is simplified by adding the latest one-year quarterly average Short-Term Debt & Capital Lease Obligation and Long-Term Debt & Capital Lease Obligation together. As of Mar. 2026, RIKEN KEIKI Co's latest one-year quarterly average Book Value of Debt (D) is 円2531.7418 Mil.
a) weight of equity = E / (E + D) = 157504.292 / (157504.292 + 2531.7418) = 0.9842
b) weight of debt = D / (E + D) = 2531.7418 / (157504.292 + 2531.7418) = 0.0158

2. Cost of Equity:
GuruFocus uses Capital Asset Pricing Model (CAPM) to calculate the required rate of return. The formula is:
Cost of Equity = Risk-Free Rate of Return + Beta of Asset * (Expected Return of the Market - Risk-Free Rate of Return)
a) GuruFocus uses 10-Year Treasury Constant Maturity Rate as the risk-free rate. It is updated daily. The current risk-free rate is 2.65%. Please go to Economic Indicators page for more information. Please note that we use the 10-Year Treasury Constant Maturity Rate of the country/region where the company is headquartered. If the data for that country/region is not available, then we will use the 10-Year Treasury Constant Maturity Rate of the United States as default.
b) Beta is the sensitivity of the expected excess asset returns to the expected excess market returns. RIKEN KEIKI Co's beta is 0.9635.
c) (Expected Return of the Market - Risk-Free Rate of Return) is also called market premium. GuruFocus requires market premium to be 6%.
Cost of Equity = 2.65% + 0.9635 * 6% = 8.431%

3. Cost of Debt:
GuruFocus uses latest TTM Interest Expense divided by the latest one-year quarterly average debt to get the simplified cost of debt.
As of Mar. 2026, RIKEN KEIKI Co's interest expense (positive number) was 円74.363 Mil. Its total Book Value of Debt (D) is 円2531.7418 Mil.
Cost of Debt = 74.363 / 2531.7418 = 2.9372%.

4. Multiply by one minus TTM Tax Rate:
GuruFocus uses the most recent TTM Tax Expense divided by the most recent TTM Pre-Tax Income to calculate the tax rate. The calculated TTM tax rate is limited to between 0% and 100%. If the calculated tax rate is higher than 100%, it is set to 100%. If the calculated tax rate is less than 0%, it is set to 0%.
The latest calculated TTM Tax Rate = 3395.852 / 13352.87 = 25.43%.

RIKEN KEIKI Co's Weighted Average Cost Of Capital (WACC) for Today is calculated as:

WACC=E / (E + D)*Cost of Equity+D / (E + D)*Cost of Debt*(1 - Tax Rate)
=0.9842*8.431%+0.0158*2.9372%*(1 - 25.43%)
=8.33%
